WINDOW.

To @ZZ whom t may concern Be it known that we, EMIL STANECKY and LEA H. STANECKY, citizens of the yUnited States, and residents of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Windows, of which the following is a specification.

Our invention relates to improvements in windows having inwardly vswinging sashes, and has for its object the provision of an improved hinge construction for permitting of such inward swinging of the window sash.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this speciiication, and in which- Figure 1 is an interior elevation of the lower portion of a window embodying our invention, Fig. 2, an enlarged sectional view showing one of the hinges in position of use, Fig. 3, a face view of the hinge, Fig. 4, a rear view of a modified form of hinge,

5, a front view of the construction illus-` trated in Fig. 4, and Fig. 6, a section taken on line G--G of Fig. 5.

rIhe preferred form of construction as illustrated in the drawing comprises a window sash mounted in the usual frame, the outer side 8 of the lower portion of one of the guide grooves for said sash being` re-l moved to permit of inward swinging thereof and said sash being provided with a suitable lock 9 to prevent such inward swinging when desired. Hinge studs 10 are secured to sash near its top and bottom on the side opposite to said removed portion. Downwardly swinging foldable socket members 11 are arranged in casings 12 mortised into the window frame, said socket members being adapted to receive hinged studs 10 when sash 7 is lowered toits bottommost position. A stop 10y is provided on the lower sash in position to engage the corresponding lower socket member upon elevation of the sash to swing said socket member upwardly into folded position. A spring 13 is also provided in casing 12 and bearing against socket member 11 to hold said socket member in either of its positions. It will Specification of Letters Patent.

Application filed. April 10, 1912.

Patented Oct. 13, 1914'. serial No. 689,935.

be observed that the lowermost stud 10 is 55 arranged in the path of the uppermost socket member so that when sash 7 is vfully raised, the lowermost stud 10 strikes the upper socket member 11 and automatically folds it into inoperative position.

In Figs. 4, 5 and 6 we have illustrated a modified form of hinge member. This construction comprises a casing 14 secured to the window frame in proper position and carrying a socket member l5 which is se- 65 cured to a trunnion 16 mounted in casing 14 as sho-wn. At its inner end trunnion 16 carries a plate 17 which in turn carries a crank pin 18 which is connected by means of a spring 19 with a pin 2O in casing 14. 70 A stop pin 21 serves to limit the downward swing of socket member 15. This furnishes a simple and efficient form of socket member.

While we have illustrated' and described 75 the preferred forms of construction for carrying our invention into effect, these are capable of variation and modification without departing from the spirit of the invention. IVe, therefore, do not wish to be limited to the precise details of construction set forth, but desire to. avail ourselves of such variations and modifications as come within the scope of the appended claim.

Having described our invention what we claim as new and desire to secure by Letters Patent is.

A window construction comprising a frame; a sash slidably and swingingly mounted in said frame; a hinge member carried by said sash; a hinge member pivoted in said frame and arranged to cooperate with said first mentioned hinge member; and a stop on saidy sash located below the hinge member thereon and arranged to engage the hinge member on said frame and fold it into inoperative position upon elevation of said sash, substantially as described.

In testimony whereof we have signed our EMIL STANECKY. LEA H. STANECKY.
